Air Toxic Study at St. Helens Elementary School

EPA found air toxics concentrations are below the levels of concern associated with health problems from short-term
or long-term exposures to acetaldehyde, manganese, and nickel or other toxic metals. While the results confirm some
impact from a nearby source, the monitored results are not as high as was suggested by the modeling data. Because
no concentrations of concern were found, monitoring has been discontinued at the school. Read more about the study
